Image processing apparatus, non-transitory recording medium storing image processing program, and image processing method for generating a color chart image data

1. An image processing apparatus comprising a processor that generates color chart image data representing a color chart containing a plurality of patches and causes a printing apparatus to print the color chart based on the generated color chart image data, wherein the processor generates the color chart image data representing the color chart in which amounts of recording agents having colors that belong to a first color group are fixed among the patches and an amount of a recording agent having a specific color that does not belong to the first color group varies among the patches, wherein the processor generates the color chart image data in which the amount of the recording agent having the specific color to be printed as an undercoat for the recording agents that belong to the first color group on a print medium varies among the patches.

2. The image processing apparatus according to claim 1 , wherein the first color group contains cyan, magenta, yellow, and black, and the specific color is white.

3. The image processing apparatus according to claim 1 , wherein the processor causes the printing apparatus to print the recording agent having the specific color on the print medium based on the color chart image data and further causes the printing apparatus to print the recording agents having the colors that belong to the first color group based on the color chart image data in a position where the recording agent having the specific color has been printed on the print medium.

4. The image processing apparatus according to claim 1 , wherein the processor controls the printing apparatus that performs printing by using a carriage that incorporates a print head that discharges ink as the recording agent and makes reciprocating movement above a print medium along a predetermined direction, and the processor specifies, in uncorrelation with the generated color chart image data, a range containing a width of the print medium in the predetermined direction as a range over which the carriage moves and causes the printing apparatus to print the color chart.

5. A non-transitory recording medium that causes a computer to perform a generation function of generating color chart image data representing a color chart containing a plurality of patches, and a print control function of causing a printing apparatus to print the color chart based on the generated color chart image data, wherein the generation function generates the color chart image data representing the color chart in which amounts of recording agents having colors that belong to a first color group are fixed among the patches and an amount of a recording agent having a specific color that does not belong to the first color group varies among the patches, wherein the generation function generates the color chart image data in which the amount of the recording agent having the specific color to be printed as an undercoat for the recording agents that belong to the first color group on a print medium varies among the patches.

6. An image processing method comprising: a generation process step of generating color chart image data representing a color chart containing a plurality of patches; and a print control process step of causing a printing apparatus to print the color chart based on the generated color chart image data, wherein the generation process step generates the color chart image data representing the color chart in which amounts of recording agents having colors that belong to a first color group are fixed among the patches and an amount of a recording agent having a specific color that does not belong to the first color group varies among the patches, wherein the generation process step generates the color chart image data in which the amount of the recording agent having the specific color to be printed as an undercoat for the recording agents that belong to the first color group on a print medium varies among the patches.
